PCBs are custom, expensive and non-returnable. That means you have to get it as close to perfect the first time or risk losing $!
One thing some people may not realize is that the EAGLECad DRC (Design Rule Check) will make sure your pads arent touching, traces aren’t crossing, drills are large enough, etc. but DRC doesn’t check for airwires!
For example, in this PCB layout, we have a DRC with no errors
But if you check the number of remaining airwires (click on the airwire tool and look at the bottom of the window) you’ll see that there are 2 of them.
When you’re done it will say “Nothing to do!” (which is a great feeling)
Remember: moving parts, changing the DRC, etc. can create little airwires. Be especially aware of shifting ground planes (which can be done by editing the DRC) that can create hairline airwires!
